Roughness of Features

Snow

The roughness of the snow element of the texture. The valid/slider range is 0 (perfectly smooth snow) to 1 (extremely rough snow). The default value is 0.4.

Rock

The roughness of the rock element of the texture. The valid/slider range is 0 (perfectly smooth rock) to 1 (extremely rough rock). The default value is 0.707.

Boundary

The raggedness of the rock/snow boundary. The valid/slider range is 0 (perfectly smooth rock/snow boundary) to 1 (extremely rough rock/snow boundary). The default value is 1.

Snow Levels

Snow_alt.

The level (altitude) of the transition between rock and snow. The valid range is 0 to infinity. The slider range is 0 to 1. The default value is 0.5.

Snow_dropoff

The suddenness with which snow no longer sticks to the mountain. The valid range is 0 to infinity. The slider range is 0 to 1. The default value is 2.

Snow_max_slope

The maximum angle (expressed as a decimal value) over which snow will not stick to the mountain. For example, where the slope exceeds the Snow_max_slope value, it would be bare rock. The valid range is 0 to infinity. The slider range is 0 to 3. The default value is 0.8.

Recursion Depth

Level_max

The maximum number of iterations used to calculate the fractal pattern, which controls how fine grained the fractal pattern is. The valid/slider range is 0 to 40. The default value is 20.
